Es spricht einiges dafür, dass die Fische weniger simpel und primitiv sind als bisher gedacht. http://www.scinexx.de/wissen-aktuell-19590-2015-12-01.html

Loading...Hallo. Es gilt seit vielen Jahren als Wissenschaftlich erwiesen, dass Fische nicht nur Schmerzen, sondern auch Emotionen empfinden können. Trotzdem will dies ein Großteil der Anglerschaft nicht akzeptieren und verweist auf Studien von Wissenschaftlern, die der Anglellobby sehr nahe stehen. Jäger hingegen handeln im allgemeinen im vollen Bewusstsein, dass sie fühlende Tiere bejagen und erkennen…
Hallo Und zwar möchte ich bei Dehner ein Kaninchen kaufen und wollte fragen wie viel die dort kosten? Liebe Grüße!
Hallo habe ein 60•30•30 Aquarium und habe darin Fadenalgen mein Aquarium ist nicht mehr in der einfahrfase und die Algen vermehren sich stark
Moin Leute, Ich habe jetzt mein Nagarium eingerichtet und der Hamster ist jetzt auch drin und wollte fragen wie ihr es findet. Das Sandbad wurde extra eingebuddelt da sonst Zerquetschungsgefahr da ist, Links ist der Wassernapf und der andere für Frischfutter
Welche fische kann man in einem 250er Becken mit Schwertträgern (7 Stück) und Antenenwelsen (4Stück) halten (1×0,4×0,5)
Bei mir auf dem Dachboden sind im Sommer tagsüber immer jede Menge Fledermäuse im Gebälk. Die kommen auch sicher bald wieder. Die fliegen immer durch die alten Eulenlöcher im Giebel ins Haus. Mein Dachdecker meint, ich soll bei den nächsten Schieferarbeiten im Winter die Eulenlöcher schließen lassen, weil er findet, dass die Fledermäuse zu viel…
Hello joerosac
The article is… well how to say it… certainly not a glowing example of careful science journalism. Or perhaps – because the conclusions of the study do not differ significantly from those of the article I think both of them are extremely susceptible to errors after a short reflection. Already the first few sentences are very liberal in dealing with words such as feelings, emotions, pain… and what does it have in this contest for a relevance to the learning ability of fish? No one.
The article wants to convey that “fish” are smarter than you mean.
What is emotional stress? What is not emotional stress?
Such a comparison is basically faulty. Linnée’s taxonomy, e.g. the traditional division into fish, amphibians, reptiles, birds and mammals, is not sensual in the case of fish and reptiles – the word “fish” is not biologically stable. There is no group called “fish” in modern taxonomy.
It would not be uncommon at all if so-called fish would differ significantly in their ability to feel feelings or pain.

So far, I’ve only been talking about it, now I’ve got to go to the inside:
This conclusion is not mandatory. It is easy to explain why zebrabärblings that are trapped in a net then show a stress reaction, and that was.
The term “emotional fever” is a lot of semantic ballast.
Seriously, done. This happens when biologists overestimate their philosophical competence.

A critique of the study.
The answer to the review:
http://rspb.roysocietypublishing.org/content/royprsb/284/1847/20162124.full.pdf
I’m clear on the side of B. Key et al.
PS
Please do not confuse the criticism of the study by the fact that the conclusions of the study must be absolutely wrong – that is something completely different. Even though the study, as I believe, cannot sufficiently support the results, it does not mean that the opposite is true. It’s just that nothing is proven in the awareness of zebrafish.
Yes they are happy when they can swim and have food.
Not really. Fish are instinct-controlled and have no emotions (e.g. happy) like people
But there is a lot to say that the fish are less simple and primitive than previously thought. http://www.scinexx.de/know-how-current-19590-2015-12-01.html
But also a lot about it. There are also studies that say the opposite
Fish also have a brain, a central nervous system and pain receptors! They can feel pain just like cats, dogs and people. Their death, which they die for the food industry, is extremely cruel: prisoners fish suffocate painfully, have pains due to the pressure drop, and often their floating bubble tears. They will disintegrate, slain, and most of them will be cut up alive on the big fishing vessels.
Although the fish is praised because of its high content of omega 3 fatty acids, food for humans is not quite harmless. According to the Federal Office for Consumer Protection and Food Safety, fish and shellfish are the main source of mercury and arsenic intake via food. Even if the findings are not yet particularly far-reaching and although fish do not scream when they are in pain and fear, their behaviour should be enough proof of their suffering when they are skewed or caught on the net. They fight to escape and show that they have a will for survival. It has been shown that fish like vertebrates also have the ability to anaesthesia. As soon as an animal is injured, opium-like substances (enkephaline and endorphine) are released. Thus, it can be concluded that a pain sensation must be present, otherwise it would hardly have any sense that such a system could develop in animals at all.
Meanwhile, the fish stocks of the seas shrink dramatically – some species are already threatened with extinction. Although we do not know in the supermarket what species are particularly threatened and which fish can be taken with good conscience. But the global demand for fish has exploded in recent years, while fish stocks in the world’s oceans are shrinking dramatically. Almost 85 % of stocks, including tuna species, redfish, plaice or North Sea cod, are considered to be overfished or are close to it, according to FAO estimates. The reasons for overfishing lie in economic interests, the world’s largest fishing starvation and increasing technologization of high sea trawlers. While Iceland and Norway are exemplary in terms of catch quotas for fish, the EU’s catch quotas are on average 35% above the catch recommended by science. In this respect the fish cannot be happy!
Fish are completely indestructible vertebrates. Even cartilage fish are vertebrates, because even with only rudimentary bony, it is the same construction plan.

Specifically, fish are the aquaticly living vertebrates, unlike terrestrially living vertebrates on land. And both the aquaticly living vertebrates and the terrestrially living vertebrates have the ability to anaesthesia.
Fish are not primitive at all. You know that fish also feel so much pain. They have all the anatomical requirements to be able to suffer mentally and physically exactly as mammals.

they have too little psychic powers.
I can’t say if my fish are happy. In any case, they are excited and beg for food. The fighting fish are a bit further from the brain than my platys and neons. They come to the pane to “play” . Whether it’s joy or instinct, be put there. In any case, some fish species can identify faces and communicate with positive or negative experiences. The fact that fish are treated properly, especially in the hobby, is presumed. Of course. At least with me.
I dare to doubt facial recognition. I rather assume that they can distinguish different people in the step. Everyone runs somehow differently and the differences are so great that AI now only needs a video clip to distinguish and recognize people. For the pressure waves, when the vibrations caused by the steps on the ground are propagating in the water, fish have finest sensors and they have learned from small to differentiate dangerous and harmless sense perceptions.
You can see faces. This has already been proven. At least in some species. https://www.ivh-online.de/presse-medien/archiv/mitteilung-des-ivh-pressedienst/news/detail/News/studie-fische-koennen-menschen-recognis.html
In the case of shoot-fishing, the elimination of the finest optical differences is vital. If they shoot on the leaf next to the insect instead of the insect, they have nothing to eat. Then the insect has flew away and no second attempt is possible. I don’t think you can transfer your highly specialized skills to all fish. Just like hunters of turbulent or dark waters are superior to the clearwater inhabitants to navigate blindly and find prey.
It’s more like the colors of the clothes. In addition, it comes to the species. My fighting fish recognize me. With my father, they watch that they win land. 😂
A friend of mine reported that his fish only know him in civilian. When he goes directly from work in warning clothing into the fish room, they do not recognize him, but are afraid.
Depends on this, there are definitely those who can look forward to it. Come on to the brain.
Yes, of course, you can see how they get wild in food, even if they can’t be hungry.
